QuickMarkup

Write and edit QuickMarkup declarative UI markup in C# projects. Use when the project uses QuickMarkup, identifiable by `using QuickMarkup.Infra`, `using QuickMarkup.SourceGen`, or `[QuickMarkup(...)]` attribute in .cs files.

How to run, update, or add snapshot tests for source generator output in Get.Parser. Snapshot tests verify generated C# code (`.g.cs`) against stored reference files to catch regressions.

Maps QuickMarkup repository areas to files for contributors implementing language, binders, codegen, source generation, or Roslyn analyzers. Use when editing QuickMarkup itself (not when consuming QuickMarkup as a library), adding syntax, AST nodes, binders, diagnostics, or generated C# output.
